Brian Toohey Biology Mrs. Heimforth 12/06/10 Diffuse the Osmosis Section 2: Introduction Step 1: The scientific concept of this lab was to see how osmosis transferred the substance through the cells to reach equilibrium. Step 2: My hypothesis was that the bag with 60% sucrose then it would be heavier than the bag with tap water or 30% sucrose. I thought this because I thought that there would be more of a substance change in 60% sucrose. Section 3: Methods First get 3 pieces of the same

Genetically Modified Organisms INTRODUCTION: The purpose of this lab was to identify if non-labeled food products are actually genetically modified foods. Before we could begin testing this theory we first had to gain an understanding about genetically modified organisms in general. This was rather easy because if you have been to any grocery store lately you have without a doubt seen products with labels saying "GMO-free" or even "contains only non-GMO ingredients." GMO actually stands for

CHN analyses were carried out on a Perkin Elmer 2400 Elemental Analyser. The elemental and spectral analyses of synthesized compounds have been carried out at SAIF Punjab University‚ Chandigarh. The purity of compounds was checked on thin layers of silica gel in various non-aqueous solvent systems‚ e.g. benzene: ethylacetate (9:1)‚ benzene: ethylacetate (8:2). Molecular weight determinations were carried out by the Rast

envy. The public is constantly bombarded with the idea that organic products are better. Perhaps this is true‚ but maybe it is brilliant marketing simply selling a status symbol. Envy can come from a neighbor’s luscious‚ organically grown front yard to the hybrid vehicle a co-worker drives‚ to the organic foods that consumers in a higher financial echelon seem to be able to only afford. Is this envy justifiable or is the notion of organics and its superiority a tactic of propaganda to boost the already

Corte Madera Scientific Report Abstract I examine how rising or falling tide can affect the water level of Corte Madera Salt Marsh in this report. The data is from Wednesday (June 19th) and Thursday (June 20th). My hypothesis is that tide and water level have positive relationship. From the result‚ I learn that the water level and tide have positive relationship. However‚ when tide changes its direction‚ the water level is likely to stay or little change. Introduction On June 19th‚ my

Purpose The purpose of this laboratory is three fold: 1. Familiarize the student with the concept and meaning of pH 2. Provide the student experience in measuring pH a. pH testing paper 3. Test the student’s hypothesis as it related to the pH of common solutions Hypothesis The pH of the tested solutions will be in the order of the following according to a pH scale: 1. Lime juice 2. Orange juice 3. Soda 4. Iced Tea 5. Milk 6. Water 7. Soapy water Material Required To facilitate

simple distillation. The steeper slope represent how fast the mixture are separated throughout the distillations. For example‚ the simple distillation for acetone the slope initially started at about 20 mL at about 65.5℃ and ended at about 30 mL at 101 ℃ in which plateau throughout the distillation. The fractional distillation started to slope at 30 mL at 62℃ and ended at 35 mL at 100℃ as it plateaus until the very end. Similarly‚ the fractional distillation for n-propanol provided better
